Definitions

  • the present invention is related to headrests for motor-vehicle seats comprising a yielding body, a pair of parallel support rods lowerly projecting from the yielding body, and height adjustment means of the yielding body relative to a seat backrest, including a series of positioning notches provided along each of said support rods and respective resilient locking members normally engaging in a disengageable fashion said positioning notches.
  • the support rods are slidably fitted within respective tubular portions, spaced apart from each other and oriented substantially vertically, of a load bearing framework incorporated within the yielding body, as disclosed for instance in FR-A-2577869 in the name of the same Applicant.
  • the support rods, rigidly connected to the load bearing framework fitted in the yielding body are slidable in a substantially vertical direction through a pair of tubular guide elements which in turn are to be rigidly connected to the structure of a seat backrest, as disclosed for instance in EP-A-0582765 and in European Patent Application No. 96830573.0, unpublished at the priority date of the present application, both also in the name of the same Applicant.
  • the object of the present invention is to overcome the above drawback, and more particularly to provide a headrest for motor-vehicle seats of the type set forth at the beginning, ensuring safe and firm retainment of the headrest yielding body on the seat backrest of the vehicle on which the headrest is installed, even in case of heavy crash.
  • the present invention provides a headrest of the above-referenced type, the primary feature of which resides in that an inertial mass is associated to at least one of said resilient locking members, said inertial mass being normally kept in an inoperative condition and movable, upon application to the headrest of a force exceeding a preset threshold value at least directed forwardly or rearwardly, to an operative condition in which said at least one resilient locking member is made at least temporarily unrealisable relative to said positioning notches.
  • said at least one resilient locking member comprises an elastically deformable element in a transverse direction with respect to the support rod and said inertial mass permanently prevents in said operative condition deformation of said elastically deformable element.
  • the inertial mass is conveniently formed by a rolling member, preferably a ball, housed within a containment body arranged on one side of the support rod and defining, above said elastically deformable element, an upper seat for unstable positioning of the ball in said inoperative condition, a lower seat for stable positioning of the ball in said operative condition, and an intermediate gravity transfer passage of said ball from the upper seat to the lower seat.
  • a rolling member preferably a ball
  • a resiliently deformable retainer member is normally associated to the upper seat of the containment body, which may be formed by a flexible tooth arranged parallelly to the support rod to clamp the ball against the containment body with a set retaining force.
  • the headrest further comprises a mounting member coupled to the ball containment body and displaceable along a transverse direction with respect to the support rod from an operative position in which it rigidly locks the ball, and an inoperative position in which said ball is solely held by said retainer member.
  • This mounting member is conveniently formed by a slider having a generally angular shape, slidably guided by said containment body and defining an axial passage for the support rod, displacement of the slider from the operative position to the inoperative position being determined by insertion of the related support rod through said axial passage upon headrest assembling.
  • the headrest comprises a pair of inertial masses each coupled to the resilient locking member of the respective support rod.
  • said resilient locking members and the respective inertial masses associated thereto are carried by the tubular portions of the load bearing framework within which the support rods are slidably fitted for height adjustment of the yielding body.
  • said resilient locking members and the respective inertial masses associated thereto are carried by the tubular guide elements through which the support rods are slidably fitted for height adjustment of the yielding body.
  • FIG. 1 is a diagrammatic and partially vertically sectioned view of a headrest for motor-vehicle seats according to the invention
  • FIG. 2 is a cross sectioned view along line II--II of FIG. 1,
  • FIG. 3 is a horizontally sectioned and enlarged view along line III--III of FIG. 1,
  • FIG. 4 is a view similar to FIG. 3 but showing a condition prior to assembling the headrest support rods
  • FIG. 5 is a vertically sectioned view along line V--V of FIG. 1,
  • FIG. 6 is a horizontally sectioned and enlarged view along line VI--VI of FIG. 1,
  • FIG. 7 is a diagrammatic front elevational and partially sectioned view of a second embodiment of the headrest according to the invention.
  • FIG. 8 is a vertically sectioned view along line VIII--VIII of FIG. 7,
  • FIG. 9 is a horizontally sectioned view along line IX--IX of FIG. 7,
  • FIG. 10 is a view similar to FIG. 9 showing a condition prior to assembling the headrest support rods.
  • FIG. 11 is horizontally sectioned view along line IX--IX of FIG. 7.
  • FIGS. 1 through 6 show a first embodiment of the invention related to a headrest of the first type mentioned at the beginning.
  • the headrest essentially comprises a yielding body or cushion 1 normally made of a foamed plastic material, incorporating a load bearing framework 2 made of a relatively rigid moulded plastic material and having a pair of spaced-apart tubular portions 3, oriented substantially vertically and opening at the base 4 of the headrest.
  • Reference numerals 5 designate two support rods each of which has an upper portion 5a slidably fitted within a corresponding tubular portion 3 of the load bearing framework 2, and a lower portion 5b intended to be rigidly anchored in a conventional way to the structure of the backrest (not shown) of a motor-vehicle seat.
  • each support rod 5 is provided with a series of positioning notches 6 cooperating with a respective normally disengageable resilient locking member 7 arranged in proximity of the lower area of the corresponding tubular portion 3. Accordingly, the height of the resilient body 1 of the headrest can be adjusted with respect to the top of the seat backrest, by means of a stepped frictioned displacement of the tubular portions 3 of the load bearing framework 2 along the upper portions 5a of the support rod 5.
  • the positioning notches 6 may conveniently be formed on a plastic material sleeve moulded over a metal core of the upper portion 5a of each support rod 5.
  • the invention provides an inertial mass safety system embodied in the load bearing framework 2 to permanently lock relative sliding between the tubular portions 3 thereof and the upper portions 5a of the respective support rods 5.
  • This inertial mass safety system is preferably (however not necessarily) dual, i.e. it is operatively associated to both support rods 5. Therefore, the following description referred to the left support rod 5 with reference to FIG. 1 can be identically applied also to the right support rod 5.
  • the resilient locking member 7 is formed by a wire spring (made of metal or of plastic material) arranged within an integral lower housing 8 of the tubular portion 3 and having two mutually crossing reaction branches 7a, 7b interconnected by an intermediate branch 7c which is resilienty deformable in a transverse direction with respect to the support rod 5.
  • the branch 7c is engaging, normally in a disengageable fashion, one of the positioning notches 6, and can be disengaged therefrom by virtue of a thrust applied to the yielding body 1 upwardly or downwardly, so as to perform height adjustment thereof.
  • the inertial mass safety system which shall now be disclosed enables preventing elastic deformation of the intermediate branch 7c, i.e. making it irreversibly non disengageable from the positioning notch 6 within which it is engaged.
  • This containment body 10 defines an upper seat 11 arranged above the resilient locking member 7 and providing unstable positioning of the ball 9 in an inoperative condition shown with full line in the drawings, and a lower seat 12 placed immediately below and in correspondence of the center portion of the intermediate branch 7c of the resilient locking member 7, for stable positioning of the ball 9 in an operative condition, shown with dotted lines in the drawings.
  • the upper seat 11 is delimited lowerly by a substantially saddle roof-like bearing member 13 (FIG. 2), and frontally by a flexible tooth 14 arranged parallely to the support rod 5 and whose function is to clamp the ball 9, in the above mentioned inoperative condition, against the containment body 10 under a set retaining force.
  • the flexible tooth 14 shall be able to release the ball 9 whenever same is subjected to a forwardly or rearwardly acceleration of about 20 g.
  • the lower seat 12 of the containment member 10 has a substantially semi-spherical shape, and is communicating with the upper seat 11 through an intermediate substantially funnel-like passage 15 through which, when coming down from the inoperative condition to the operative condition, the ball 9 released by the flexible tooth 14 rolls under gravity from the upper seat 11 to the lower seat 12.
  • the ball 9 is shown by full line in its inoperative condition, while its operative condition is depicted in dotted lines.
  • the dotted lines also show the ball 9 in either one of two possible positions taken thereby within the intermediate passage 15 when released by the flexible tooth 14, before reaching the lower seat 12.
  • Reference numeral 16 designated a mounting member formed by a generally angularly shaped slider slidably coupled with the containment body 10, in the upper area thereof, in a transfer direction with respect to the support rod 5.
  • the mounting member 16 defines an axial passage 17, whose shape is complementary to the cross section of the support rod 5, and is formed with a pair of outer lateral recesses 18 for releasable coupling with a pair of retaining springing inner arms 19 integrally formed with the containment body 10.
  • the mounting member 16 has a central front recess 20 whose shape is complementary to that of the flexible tooth 14, opening into a front seat 21.
  • FIG. 4 shows the mounting member 16 in a temporary operative position, in which this member is fitted within the containment body 10, with the lateral recesses 18 engaged by the springing arm 19.
  • the axis of the axial passage 17 is offset relative to the axis of the tubular portion 3, the recess 20 houses therein the flexible tooth 24 so as to prevent deflection thereof, and the front seat 21 engages the ball 9, so as to prevent any displacement thereof. Accordingly, the yielding body 1 with the load bearing framework 2 embodied therein can be handled without any need of particular caution, in view of following assembling thereof with the support rods 5.
  • the upper portion 5a of the support rod 5 When the upper portion 5a of the support rod 5 is fitted into the respective tubular portion 3 of the load bearing framework 2, it engages the axial passage 17 thus causing extraction of the mounting member 16 relative to the containment body 10, following disengagement between the springing arms 19 and the lateral recesses 18.
  • the mounting member 16 is thus shifted until the axis of the axial passage 17 is centered with the axis of the tubular portion 3, i.e. of the support rod 5, such as shown in FIG. 3. Due to this displacement, the front seat 21 moves away from the ball 9, which is then kept in its inoperative condition solely by the flexible tooth 14, which in turn is now disengaged from the recess 20. Return of the mounting member 16 to its operative position of FIG. 4 is no longer possible owing to the presence of the support rod 5 through the axial passage 17.
  • the ball 9 In use of the headrest, in normal conditions the ball 9 is held in its inoperative condition, and height adjustment of the headrest relative to the backrest of a motor-vehicle seat can be performed in a usual way by raising or lowering the yielding body 1 along the support rods 5. Elastic deformation of the intermediate branch 7c of the resilient locking member 7 thus enables, by virtue of engagement and disengagement thereof relative to the positioning notches 6, to carry out a stepped frictioned adjustment of the height position of the yielding body 1.
  • the transition of the ball 9 from the inoperative condition to the operative condition will occur whenever the headrest is subjected to a force, exceeding the preset threshold value, directed forwardly or rearwardly with respect to the longitudinal direction of the vehicle.
  • a force exceeding the preset threshold value
  • Naturally expedients may be also contemplated so as to achieve the same effect even with respect of forces directed transversally of the longitudinal direction of the vehicle, i.e. in case of lateral crash.
  • FIGS. 7 through 11 show an alternative embodiment of the invention, corresponding to a headrest of the second type defined at the beginning, i.e. wherein the upper portions 5a of the support rods 5 are fixedly connected (in a way known per se and thus not shown in detail) to the load bearing framework 2 of the yielding body 1, and in which height adjustment of the headrest is performed by means of a slidable coupling between the lower portions 5b of the support rods 5 and the backrest S of a motor-vehicle seat.
  • parts which are identical or similar to those already previously disclosed with reference to FIGS. 1 through 6 are indicated by the same numeral references.
  • the inertial mass safety system can be associated only to one or instead to both support rods 5: accordingly the following description referred to one of these support rods 5 can be identically applied also to the other one.
  • the lower portion 5b of the support rod 5 is formed with the positioning notches 6 and is slidably fitted through a respective tubular guide element, generally designated as 23, in turn rigidly secured to the framework of the backrest S.
  • a respective tubular guide element generally designated as 23, in turn rigidly secured to the framework of the backrest S.
  • the arrangement disclosed with reference to the tubular guide element 23 shown in the drawings identically applies also to the other not shown tubular guide element.
  • the tubular guide element 23 is formed by a plastic material bush moulded, in correspondence of a rear thickened section 24 thereof, over a non-circular cross section portion 25 of a metal bar 26 constituting the upper transverse member of the framework of the backrest S. It is however to be pointed out that this arrangement, though quite advantageous, is purely indicative, since the tubular guide elements 23 may simply be formed by metal sleeves fixed to the metal bar 26 by welding.
  • the lower portion 5b of the support rod 5 is frictionally slidable through the bush 23 so as to enable height adjustment of the yielding body 1 of the headrest relative to the top of the seat backrest S.
  • the notches 6 cooperate with the intermediate branch 7c of the resilient locking member 7 fitted within the containment body 10 in turn housed in a lower integral housing 27 of the bush 23.
  • the containment body 10 may be integrally formed with the bush 23 by moulding.
  • the resilient locking member 7 may have a different design than the one disclosed in the above, and also the inertial mass 9 might be designed differently than a ball, and be for instance constituted by a roller or the like.
  • the mounting member 16 might be suppressed and replaced by functionally equivalent expedients.
